The Restep power system is designed using open source and/or free software wherever possible. KiCad is used for the schematic capture and PCB design, LTSpice is used for circuit simulations, PTC Mathcad is used for calculations, and Arduino IDE is used to program the micro controller. Microsoft Excel is the only licensed component, but it's not entirely necessary. All documentation is available as open source on the restep-eco GitHub repository.
